Just for curiousity I took some pics with a thermal imaging camera. Why is it that the manifold runs hottest towards the centre?
Here is the muffler. You can see how it heats the differential.
And of course, the radiator.
Cool stuff, John. Thanks.
You'll be posting more shots I hope.
I would say because it is getting directly heated by two cyls as well as some of the heat from cyl #1. Cool pics!
I would think because of the higher concentration of heat and less mass. The center "sees" the exhaust gasses from three cylinders. The firing order is 1-2-4-3 followed by 1-2...
Interesting photos. What model of FLIR are you using.
What about the floor right above the exhaust pipe?
Neat photo's, many thanks!!
It's a creepy experience walking around the house in the dark with the camera - you can see all the framework in the walls. Will be useful this winter to see where the heat leaks out.
I'll be taking the T for a long drive on Saturday so might take some more pics.
It's a Flir i7 which my employer has only just bought...and I get to look after it
found another one still in the camera
John, So what type of camera is that? What kind of money and can a dummie use one? Thanks, Scott
Interesting photos. Others have reported that the #3 and #4 cylinders run hotter then #1 and #2. Would is be possible for you to get a photo of the drivers side of the block showing the cylinders?
Jim, that is the Driver's side. The car is a RHD car in Australia. You would like a passenger side pic! :-)
I hadn't noticed before although it's clearly obvious in the pic - #2 & #3 exhaust ports are much closer to each other than the others. Therefore, less area to dissipate the heat.
Scott, it's a Flir i7 thermal imaging camera. They're not cheap - $995 in Australia (it would cost less in the U.S. of course) and that was with a huge discount because it was bought for an educational institution. It works like any other digital camera; point, shoot, and download via a USB cable. No setting up involved.
It's an incredibly useful fault finding tool. For example, you can see where switches and electrical connections are likely to fail; e.g bad starter motor connection. In the case of the Model T you can see how well the radiator is working, or if it's running too lean, even things like if the handbrake is equalised (drums should be the same temp as each other), etc.
I'd expect the price to eventually come down like all these things do, so then we can all afford our own.
If you only want the temperature measurements, an infra red thermometer will do that for a lot less; way under $100. I use one for refrigeration work.
I once worked as a paid 1st mate on the back of a very large Viking sport fisherman. known as back boys, we run the back of the boat during marlin tournaments. one of the non fishing benefits was using the flir at the dock to see which woman were in fact woman and which woman were natural or augmented from the heat signature. because the girls all look prettier at closing time!
It would be interesting to take a image of the Vaporizer carburetor to see how "pre-heated" some areas might be during the running process.
That's just absurdly cool. The prices I'm finding here in the US are all about $2,000.
You need to drive the car Saturday and then take pics of the whole thing all over. Even better see if you have someone else drive and you take pics while you are riding down the road! Compare those with pics of the car sitting still and idling. It'd be really neat to see side by side comparisons of the heat on different parts when the wind is cooling the radiator and when there's just the fan running.
I was expecting to see a higher temperature on the manifold and see why now. The limit on i7 is 250C. That explains that. Just checked the US prices. They're right around $2k here for the same model.
The front radiator shot is great. Shows the effect of cooler air being drawn in by the fan. Who was it that said you don't need a fan?
they are a must for diagnosing wet exhaust marine systems. unless you want to just replace everything, and my customers don't!
With a thermostat and waterpump, and no fan, and going more than 5 mph, Ken, all the water in the radiator is cool. I never see red in the motometer, except when engine running while stopped.
With a thermostat, only the water in the block has to heat up to operating temp, and not the entire load of water, as shown in the third pic.
Is that radiator a new replacement or an original I wonder. It would be interesting to see a side by side comparison.
The radiator is new (Bergs).
Left hand side of engine:
Floor above exhaust pipe:
Back of transmission; you can see where the oil is when the engine is off:
Under front of car:
RHD floor, oooh that looks hot on the drivers feet.
I use asbestos around my exhaust, l am wondering how much heat it stops coming thru the floorboards to the passengers feet???
Very interesting and looks like you can have fun and learn at the same time. I can see this camera would come in pretty handy for estimates of repair at my shop when customers want an instant answer to their questions.
Interesting to see the front of the radiator with the heat at the top and the cooler circle at the center in front of the fan. Amazing how hot the transmission gets too.
